Central Bulk Fill System Having Stowable Ladder For Stack-Fold Farm Implement

Abstract

A stack-fold implement having a central bulk fill hopper assembly is provided. The bulk fill hopper assembly is mounted to the center frame section of the stack-fold implement and does not affect the narrowness of the stack-fold implement when it's in a stacked, transport position. The hopper assembly includes a pair of bulk fill hoppers or tanks supported by cradle that is in turn supported by a pair of wheels. The cradle is removably coupled to the center frame section by a plurality of rigid frame members. A retractable ladder may be stowed beneath the hopper assembly.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to farm implements and, more particularly, to a central fill system having a stowable ladder for a stack-fold planter.[0002]Increasingly, farm implements have been designed to have frames that can be folded between field-working and transport positions. One such type of farm implement is a stack-fold planter, such as the 1230 Stackerbar planter from Case New Holland, LLC. Stack-fold planters generally consist of a center frame section and a pair of wing frame sections. In the field-working position, the wing frame sections are evenly aligned with the center frame section. In the transport position, however, the wing sections are lifted to a position directly above the center frame section, i.e., to a “stacked” position. In the stacked position, the width of the implement is generally that of the center frame section, thus making the implement better suited for transport along roads and between crops.[0003]Opene...

Benefits of technology

[0006]The present invention is directed to a central fill system having a stowable ladder for use with a stack-fold implement. The bulk fill hopper assembly is mounted to the center frame section of the stack-fold implement and does not affect the narrowness of the stack-fold implement when in a stacked, transport position. The hopper assembly preferably includes a pair of bulk fill hoppers or tanks supported by cradle that is in turn supported by a pair of wheels. The cradle is removably coupled to the center frame section by a pair of rigid frame members. Parallel linkages interconnected the cradle and the wheels, and allow the wheels to, in ef

Problems solved by technology

Larger seed boxes, however, have drawbacks.

The additional material that can be carried by larger seed boxes adds to the overall weight of the openers, including those mounted to the wing sections.

This additional weight can stress the lifting/lowering system that stacks the wing sections, or require a more robust system, which can add to the overall size, mass, complexity, and cost of the implement.
